Description GEnx-1B, GEnx-1B/P1 and GEnx-1B/P2 models: The GEnx-1B engine is a dual rotor, axial flow, high bypass ratio turbofan. The 10-stage high pressure compressor is driven clockwise (Aft Looking Forward) by a 2-stage high pressure turbine. The single stage fan and 4-stage low pressure compressor are driven counterclockwise (Aft Looking Forward) by a 7-stage low pressure turbine. The engine control system includes a Full Authority Digital Engine Control (FADEC), which has an aircraft connection for digital communication. An engine monitoring unit (EMU) provides vibration level signals to the aircraft. TE.CERT.00052-001 European Aviation Safety Agency, 2018. All rights reserved. ISO9001 Certified. Page 7 of 20

Notes 1. Engine Ratings Engine ratings are based on calibrated test stand performance under the following conditions: A. Sea level static, standard pressure 101,3 Pa (14.696 psia), 15 deg C B. No customer bleed or customer horsepower extraction C. Ideal inlet, 100% ram recovery D. Production aircraft flight cowling E. Production instrumentation F. Fuel lower heating value of 8813 kj/kg. 2. Takeoff Time Limits The normal 5-minute takeoff time limit may be extended to 10 minutes for engine out contingency. 3. Life Limits The EASA approved Airworthiness Limitations Section of the Instructions for Continued Airworthiness is published in Chapter 5 of the GEnx Engine Manual, GEK 112851 for GEnx-1B54, -1B58, -1B64, -1B67, -1B70, -1B54/P1, -1B58/P1, -1B64/P1, -1B67/P1, -1B70/P1, -1B70/72/P1, -1B70/75/P1, -1B74/75/P1, -1B75/P1, -1B54/P2, -1B58/P2, -1B64/P2, -1B67/P2, -1B70/P2, -1B70/72/P2, -1B70/75/P2, -1B74/75/P2, -1B75/P2, -1B76/P2, -1B76A/P2 and -1B78/P2. For the GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P this is published in Chapter 5 of the GEnx Engine Manual GEK 114119. The GEnx-1B, GEnx-1B/P1, and GEnx-1B/P2 and GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P cyclic life limits are based on a commercial mission cycle, which consists of a start, takeoff, climb, cruise, descent, and landing. Use (or non-use) of a fan reverser for braking during landing does not affect cycle counts. Each of the following constitutes one cycle: (1) a flight consisting of a takeoff and landing, (2) a touch-and-go landing or simulated touch-and-go landing (no weight on wheels) for pilot training.

4. Fan Blade Criticality and Repair For the purposes of the EASA Validation the Fan Blade is declared as an Engine Critical Part. Approval of repairs of the fan blade composite material in the root section of the fan blade up to the inner annulus flow path line must be coordinated with the Airworthiness Agency. Substantiation of the repairs must show that compliance to GEnx-1B and -2B Special Condition GEnx CRI-T5 is maintained. 5. Induction System Icing Demonstration of compliance for Induction System Icing, is installation specific to the Boeing B787-8 model aircraft for the GEnx-1B, GEnx-1B/P1, and GEnx-1B/P2 engine models and B747-8 for the GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P engine models. Installation of these engine models on different airplane models or type will require a separate evaluation and finding of compliance. 6. Thrust Setting Parameter Power setting, power checks, and control of engine thrust output in all operations are based on Fan Speed (N1). Speed sensors are included in the engine assembly for this purpose. 7. Icing Conditions (1) For ground operation in icing conditions, requirements, limitations, and notes are specified in GEnx-1B, GEnx-1B/P1, and GEnx-1B/P2 Operating Instructions Manual GEK 112857 and GEnx- 2B67, GEnx-2B67B, and GEnx-2B67/P Operating Instructions GEK 114113. (2) For engine operation in ice crystal cloud conditions limitations are specified in GEnx-1B, GEnx- 1B/P1, and GEnx-1B/P2 Operating Instructions Manual GEK 112857 and GEnx-2B67, GEnx- 2B67B, and GEnx-2B67/P Operating Instructions GEK 114113. The Temporary Deviation to CS-E 780 Tests in ice forming conditions for the GEnx 2B67/P model is recorded closed at TCDS issue 7 with compliance having been established by provision of the following modifications: FADEC software C075 (or later) and booster outlet guide vane assembly to propulsor group 2330M20G12 standard (or later). 8. Negative-G Operation During "negative-g" operation only, it is permissible to operate below minimum oil pressure for a maximum of 15 seconds. See GEnx Operating Instructions, GEK 112857, Section 8, for GEnx-1B, GEnx-1B/P1, and GEnx-1B/P2 definition of minimum oil pressure. See GEnx Operating Instructions, GEK 114113, Section 8, for GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P definition of minimum oil pressure. 9. Aircraft Models The GEnx-1B, GEnx-1B/P1, and GEnx-1B/P2 engine models are limited to installation on the Boeing B787-8 model aircraft only with respect to the installed power response characteristics. The GEnx- 2B67, GEnx-2B67B, and GEnx-2B67/P engine models are limited to installation on the Boeing TE.CERT.00052-001 European Aviation Safety Agency, 2018. All rights reserved. ISO9001 Certified. Page 18 of 20
B747-8 model aircraft only with respect to the installed power response characteristics. Any bill-ofmaterial changes that could significantly and adversely affect power response will have to be reassessed. 10. Fan Reverser Boeing 787-8 Aircraft/GEnx-1B Engine Series Fan Reversers: LH Wing: 721Z3030-103, 721Z3040-103 RH Wing: 721Z3050-103, 721Z3060-103 Boeing 747-8 Aircraft/GEnx-2B Engine Series Fan Reversers: LH Wing: 608C0100-565, 608C0100-566, 608C0100-567, 608C0100-568 RH Wing: 608C0100-571, 608C0100-572, 608C0100-573, 608C0100-574 11. ETOPS Limitations For the GEnx-1B54, -1B58, -1B64, -1B67, 1B70, -1B54/P1, -1B58/P1, -1B64/P1, -1B67/P1, -1B70/P1, -1B70/72/P1, -1B70/75/P1, -1B74/75/P1, -1B75/P1, -1B54/P2, -1B58/P2, -1B64/P2, -1B67/P2, -1B70/P2, -1B70/72/P2, -1B70/75/P2, -1B74/75/P2, -1B75/P2, -1B76/P2, -1B76A/P2 and -1B78/P2 engine models installed on B787 aircraft, the engine fuel pump must be replaced prior to the next ETOPS flight after any single suction feed operation event of duration greater than 30 minutes. Suction feed operation is defined by engine pump inlet fuel pressure less than the greater of true vapor pressure plus 5.0 psi or ambient plus 5.0 psi. Note that ETOPS eligibility does not constitute airplane or operational level approvals necessary to conduct ETOPS flights. 12. Flow Split Value Fuel Accumulator Applicability The GEnx-2B67 (defined by the GEnx-2B67G01 and GEnx-2B67G02 model lists) for the B747-8 aircraft will not support the installation of the flow split valve fuel accumulator system. Fuel accumulator system installation is required in order to eliminate post-engine shutdown intermittent fuel releases and observed vapors. TE.CERT.00052-001 European Aviation Safety Agency, 2018.
